Patent GB-2316978-A (GB)
Title: Adjustable seat
Inventor: CASSIDY STEPHEN MICHAEL
IPC: A47D13/10
Filed: 1996-09-04
Abstract: An adjustable seat comprising first and second supporting parts 10, 12 interconnected by a pair of hinge assemblies 14, such that the supporting parts can be pivoted with respect to one another to allow a backrest of the seat to recline. The hinge elements are configurable by an operating plunger between an unlocked condition in which the backrest can be hingedly moved in relation to one another and a locked condition in which the backrest is fixed. Placement of the hinge element 14 in its unlocked condition is inhibited unless the seat parts are manually moved to a position away from that which they will move to under the influence of gravity alone. The result is that the hinges cannot be released without first supporting the seat backrest, thereby reducing the likelihood of the backrest dropping rapidly under the influence of gravity.

Title: Packet filter compiler program
Inventor: XIANG JING
IPC: G06F9/44
Filed: 1998-10-06
Abstract: Disclosed is a computer program, driven by a graphical user interface (GUI), for building packet filters for use in a networked environment. The graphical user interface is adapted to assist a user in the construction and design of a packet filter such that the user is able to build a packet filter without being extensively trained in all of the numerous parameters involved in packet filter construction: this may be through the use of a wizard (1100) for inexperienced users or via a calculator type interface (1200) for more experienced users. In one embodiment, the program receives expression-based statements from the user. These expression-based statements indicate the design characteristics of the packet filter which the user wishes to build. The program compiles the expression-based statements into a language which is suitable for the formation of the packet filter. Finally the packet filter builder creates the packet filter desired by the user by combining a sequence of compiler statements.
